Transmission Problems Common Due to Front Pump Failure on Mercury Grand Marquis

Problem Description

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

MINE WILL SLIP, WHEN GOING AT AN EVEN SLOWER SPEED, TRYING TO GO UP A GEAR, IT HUNTS FOR THE GEAR FOR AWHILE AND THE ENGINE REVS, BUT CANNOT FIND THE GEAR FOR AWHILE. THEN IT FINDS THE GEAR AND IT IS FINE.

Whining noise in low gear, changing frequency as it slips into 2nd gear. Some of the same noise as it accelerates in 2nd gear. Not noticable after gets in 3rd and 4th. Ford dealer says it's common and not a problem as long as the car isn't loosing power. (DUH).

The car was running fine until I got in it yesterday and started it, I put in reverse backed out then neutral then put in drive and it died. It will start and run perfect in reverse but dies every time I put it in drive

just after buying car few years ago car whined in and out of gear then catch be ok. we got it checked but brought it back several times right after warenty exspired they told us we need a rebuilt transmishion. so upseting 3,000 later..
